Bisazo photo-receptor for electrophotography

ABSTRACT

An electrophotographic photoreceptor having on a conductive support a photoconductive layer containing a specific azo compound is disclosed.

FIELD OF THE INVENTION

The present invention relates to a photo-receptor for electrophotography, more specifically to a photo-receptor for electrophotography which possesses a photosensitive layer containing a particular azo compound.

BACKGROUND OF THE INVENTION

As a conventional type of photo-receptor for electrophotograghy, inorganic photo-receptor having a photosensitive layer whose principal component is an inorganic photoconductive compound such as selenium, zinc oxide, cadmium sulfide, and silicone, has been in wide use. However, these photo-receptors are not necessarily satisfactory in terms of sensitivity, thermostability, moisture resistance, and durability. For example, when selenium is used as a photo-receptor, it easily deteriorates when it is crystallized, which can cause difficulty in manufacturing selenium. Also, it can be crystallized by heat and fingerprints. Cadmium sulfide has problems with moisture resistance durability, and zinc oxide has problems with durability.

To overcome the shortcomings inherent in the foregoing inorganic photo-receptors, research and development has actively been made to develop organic photo-receptor having organic photoconductive layers whose primary components are a variety of organic photoconductive compounds. For example, Japanese Patent Publication No. 10496/1975 discloses an organic photo-receptor having a photosensitive layer containing poly-N-vinylcarbazole and 2, 4, 7-trinitro-9-fluorenone. However, this photo-receptor is not necessarily satisfactory in terms of sensitivity and durability. To improve these shortcomings, attempts have been made to allot different substances to different functions, i.e., carrier generation and carrier transport, thereby to develop organic photo-receptors of higher-performance. This so-called function-separating type of photo-receptors has been the subject of many studies because the respective materials can be selected from wide variety of compounds and, for this reason, it has been expected to obtain photo-receptors with arbitrary proparties.

In the function-separating type photo-receptors, numerous number of compounds have been proposed as carrier-generation substances. As an example in which an inorganic compound is used as a carrier-generation substance amorphous selenium as disclosed in Japanese Patent Publication No. 16198/1968 may be mentioned. This compound is used in combination with an organic photoconductive compound, however, it cannot overcome the shortcomings of an amorphous selenium, which is liable to be crystallized by heat, leading to the deterioration of its properties as a photo-receptor.

Many other proposals have been made for photo-receptors for electrophotography using organic dyes and organic pigments as carrier-generation substances. For example, Japanese patents Open to Public Inspection Nos. 22834/1979, 73057/1980, 117151/1980, and 46237/1981, refer to the use of bis-azo compounds in the photosensitive layer. Those bis-azo compounds are, however, not necessarily satisfactory in terms of sensitivity, residual electric potential or stability in the repeated use, and in vie of its limited selection range of carrier transport substances. Thus they cannot fulfill the broad requirements of the electrophotographic process.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a photo-receptor for electrophotography which contains a specific azo compound having superior carrier generation ability.

Another object of the present invention is to provide a photo-receptor for electrophotography having high sensitivity, small residual electric potential and high durability as well as improved durability in the repeated use.

Still another object of the present invention is to provide a photo-receptor for electrophotography which contains an azo compound which can also act as an effective carrier-generating substance in combination with a broad range of carrier transport substances.

The azo compound expressed by the above mentioned General formula [I] of the present invention can be easily synthesized by a known process.

EXAMPLE OF SYNTHESIS 1 (Synthesis of an illustrated compound I-71)

2.89 g (0.01 mol) of 2, 7-diamino-4-brom-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.40 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the above solution while maintaining the temperature at 5° C. or lower. After such a solution continued to be further agitated for 1 hour at the above temperature, insoluble substances were removed by filtration, and a solution prepared by dissolving 4.6 g of 6-ammonium phosphate fluoride in 50 mL of water was added to the resulting filtrate. The precipitated tetrazonium salt was obtained by filtration and was then dissolved in 100 mL of N, N-dimethylformamide (DMF). A solution formed by dissolving 6.62 g (0.02 mol) of 2-hydroxy-3-naphthoic acid-3'-trifluoromethylanilide in 200 mL of DMF was further added in drops to the above solution with the temperature being kept at 5 ° C. or lower.

With the temperature being continuously kept at 5° C. or lower, a solution formed by dissolving 6 g (0.04 mol) of triethanolamine in 30 mL of DMF was added in drops, followed by agitation for 1 hour at 5° C. or lower and further for 4 hours at the room temperature. After the reaction, the precipitated crystals were obtained by filtration, washed with DMF and then with water and dried, thus resulting in 8.71 g of the target substance.

Theoretical value:

C=60.5%, H=2.77%, and N=8.63%.

Found value:

C=60.1%, H=2.95%, and N=8.72%.

EXAMPLE OF SYNTHESIS 2

(Synthesis of an illustrated compound I-219)

2.89 g (0.01 mol) of 2, 7-diamino-4-brom-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.40 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the foregoing solution while maintaining the temperature at 5° C. or lower. After further agitation for 1 hour at the above temperature, insoluble substances were removed by filtration, and a solution formed by dissolving 4.6 g of 6-ammonium phosphate fluoride in 50 mL of water was added to the resulting filtrate. The precipitated tetrazonium salt was obtained by filtration and was then dissolved in 100 mL of N, N-dimethylformamide (DMF). A solution formed by dissolving 8.40 g (0.02 mol) of 2-hydroxy-3- (3'-trifluoromethylphenylcarbamoyl) benzo [a] carbazole in 200 mL of DMF was added in drops with the temperature being kept at 5° C. or lower.

With the temperature continuing to be kept at 5° C. or lower, a solution formed by dissolving 6 g (0.04 mol) of triethanolamine in 30 mL of DMF was added in drops, followed by agitation for 1 hour at 5° C. or lower and further for 4 hours at the room temperature. After the reaction, the precipitated crystals were gained by filtration, washed with DMF and then washed with water, and were then dried, thus resulting in 5.2 g of the target substance.

Theoretical value:

C=63.6%, H=2.87%, and N=9.73%.

Found value:

C=63.4%, H=2.97%, and N=10.01%.

In the same process as described in the above mentioned Example of Synthesis 1, the other compounds of the present invention can also be prepared by producing diazonium salts with use of the respectively corresponding amino compounds and then allowing such salts to react with 2-hydroxy-3-naphthoic acid-substituted anilide or 2-hydroxy-3- (substituent phenylcarbamoyl) benzo [a]-substituted or unsubstituted carbazole.

The example of the halogen atom for R₁₁ and R₁₂ in General formula [II] can be illustrated as a chlorine atom, a bromide atom and an iodine atom, among which chlorine atom or bromide atom is preferable.

The bio-azo compound represented by the above mentioned General formula [II] of the present invention can be easily synthsized by a known process.

EXAMPLE OF SYNTHESIS 3 (Synthesis of an illustrated compound II-6)

2.38 g (0.01 mol) of 2, 7-diamino-3, 5-dimethyl-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.40 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the foregoing solution while the temperature was maintained at 5° C. or lower. After said solution was agitated for 1 hour at this temperature, insoluble substances were removed by filtration, and a solution formed by dissolving 4.9 g of 6-ammonium phosphate fluoride in 50 mL of water was further added to the resulting filtrate. The precipitated tetrazonium salt was obtained by filtration and was dissolved in 100 mL of N, N-dimethylformamide (DMF). With the temperature kept at 5° C or lower, this solution then underwent addition in drops of a solution formed by dissolving 5.94 g (0.02 mol) of 2-hydroxy-3-naphthoic acid-3'-chloranilide in 200 mL of DMF.

Continuing to be maintained at 5° C. or lower, the above solution further underwent addition in drops of a solution of 6 g (0.04 mol) of triethanolamine dissolved in 30 mL of DMF, followed by agitation for 1 hour at 5° C. or lower and for 4 hours at the room temperature. After the reaction, the precipitated crystals were obtained by filtration, and were washed with DMF and then with water to be dried, thus resulting in 5.6 g of the target substance.

Theoretical value:

C=68.79%, H=3.74%, and N=9.82%.

Found value:

C=68.95%, H=3.86%, and N=9.98%.

EXAMPLE OF SYNTHESIS 4 (Synthesis of an illustrated compound II-583)

3.24 g (0.01 mol) of 2, 7-diamino-3-bromo-5-chloro-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.40 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the above solution while it was maintained at 5° C. or lower. After the solution thus prepared was agitated for 1 hour at the above temperature, insoluble substances were removed by filtration, and the resulting filtrate then received a solution formed by dissolving 4.9 g of 6-ammonium phosphate fluoride in 50 mL of water. The precipitated tetrazonium salt was gained by filtration and was then dissolved in 100 mL of N, N-dimethylformamide (DMF). 5.94 g (0.02 mol) of 2-hydroxy-3-naphthoic acid-3'-chloranilide was dissolved in 200 mL of DMF, and the resulting solution was added in drops to the above mentioned solution while the temperature was kept at 5° C. or lower.

With the temperature continuing to be kept at 5° C. or lower, a solution formed by dissolving 6 g (0.04 mol) of triethanolamine in 30 mL of DMF was added in drops, followed by agitation for 1 hour at 5° C. or lower and further for 4 hours at the room temperature. After the reaction, the precipitated crystals were obtained by filtration, and washed with DMF and then with water, and were then dried, thus resulting in 5.3 g of the target substance.

Theoretical value:

C=59.99%, H=2.76%, and N=8.93%.

C=60.01%, H=2.8%, and N=8.97%.

The other compounds of the present invention can be prepared, in the same process as in the above mentioned Example of Synthesis 1, by forming a tetrazo product with use of 2, 7'-diamino-4, 6-substitution-9-fluorenone and then allowing the reaction of 2-hydroxy-3-naphthoic acid-substituted anilide.

The halogen atoms of R₂₁ in General formula [III] can be illustrated by such examples as chlorine atom, bromide atom and iodine atom, among which the chlorine or bromide atom is preferable.

Preferable as the alkyl group of R₂₁ is an alkyl group having 1 to 4 carbon atoms, for example, a methyl, ethyl, isopropyl, t-butyl or trifluoromethyl group.

The alkoxy group for R₂₁ is preferably an alkoxy group having 1 to 4 carbon atoms, which can be illustrated by, for example, a methoxy, ethoxy, isopropoxy, t-butoxy group, or 2-chloroethoxy group.

Among the examples of R₂₁, preferable are a halogen atom, an alkyl group and an alkoxy group.

The alkyl group, alkoxy group and halogen atom as represented by R₂₂ to R₂₆ can be illustrated by the same specific examples as those described in relation to R₂₁ mentioned above.

In the next, the specific examples of the azo compound represented by the above mentioned General formula [III] will be described, but the azo compounds of the present invention are in no way limited by such examples.

The bio-azo compound represented by the above mentioned General formula [III] of the present invention can be easily synthesized by a known process.

EXAMPLE OF SYNTHESIS 5 (Synthesis of an illustrated compound III-7)

2.24 g (0.01 mol) of 2, 7-diamino-4-methyl-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.40 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the above solution while maintaining the temperature at 5° C. or lower. After this solution continued to be agitated further for 1 hour at this temperature, insoluble substances were removed by filtration, and the resulting filtrate then received the addition of a solution formed by dissolving 4.9 g of ammonium phosphate fluoride in 50 mL of water. The precipitated tetrazonium salt was obtained by filtration and was then dissolved in 100 mL of N, N-dimethylformamide (DMF). With the temperature kept at 5° C. or lower, a solution formed by dissolving 5.94 g (0.02 mol) of 2hydroxy-3-naphthoic acid-3'-chloranilide in 200 mL of DMF was added in drops to the above solution.

With the temperature being continuously kept at 5° C. or lower, a solution formed by dissolving 6 g (0.04 mol) of triethanolamine in 30 mL of DMF was added in drops, followed by agitation for 1 hour at 5° C. or lower and further for 4 hours at the room temperature. After the reaction, the precipitated crystals were obtained by filtration, washed with DMF and then with water, and then dried, thus resulting in 5.6 g of the target substance.

Theoretical value:

C=68.5%, H=3.56%, and N=9.98%.

Found value:

C=68.22%, H=4.01%, and N=10.01%.

EXAMPLE OF SYNTHESIS 6 (Synthesis of an illustated compound III-114)

2.89 g (0.01 mol) of 2, 7-diamino-4-brom-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.40 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the above solution while the temperature was kept at 5° C. or lower. After this solution was continuously agitated further for 1 hour at this temperature, insoluble substances were removed by filtration, and a solution was formed by dissolving 4.9 g of 6-ammonium phosphate fluoride in 50 mL of water and added to the filtrate. The precipitated tetrazonium salt was gained by filtration and was then dissolved in 100 mL of N, N-dimethylformamide (DMF). With the temperature being kept at 5° C. or lower, the solution was allowed to have the addition in drops of a solution formed by dissolving 5.94 g (0.02 mol) of 2-hydroxy-3-naphthoic acid-3'-chloranilide in 200 mL of DMF.

With the temperature being continuously maintained at 5° C. or lower, a solution made by dissolving 6 g (0.04 mol) of triethanolamine in 30 mL of DMF was added in drops to the above solution, followed by agitation for 1 hour at 5° C. or lower and further for 4. hours at the room temperature. After the reaction, the precipitated crystals were obtained by filtration, washed with DMF and then with water, and were then dried, thus resulting in 5.2 g of the target substance.

Theoretical value:

C=62.28%, H=2.98%, and N=9.27%.

Found value:

C=62.33%, H=3.05%, and N=9.38%.

EXAMPLE OF SYNTHESIS 12 (Synthesis of an illustrated compound IV-1006 represented 7 by General formula [IV-S])

3.08 g (0.01 mol) of 2, 6-diamino-1-methoxy-7-trifluoromethyl-9-fluorenone was dispersed in 10 mL of hydrochloric acid and 20 mL of water, and a solution formed by dissolving 1.4 g (0.02 mol) of sodium nitrite in 5 mL of water was added in drops to the above solution while the temperature was maintained at 5° C. or less. After this solution was continuously agitated for 1 hour at this temperature, insoluble substances were removed by filtration. Then, a solution formed by dissolving 4.6 g of 6-ammonium phosphate fluoride in 50 mL of water was added to the resultant filtrate. The precipitated tetrazonium salt was obtained by filtration and was then dissolved in 100 mL of N, N-dimethylformamide (DMF). Being kept at 5° C. or lower, this solution underwent the addition in drops of a solution formed by dissolving 7.89 g (0.02 mol) of 2-hydroxy-3-(2, 4, 6-trimethylphenylcarbamoyl)-benzo[a]carbazole in 200 mL of DMF.

While maintaining the solution at 5° C. or less, a solution formed by dissolving 6 g (0.04 mol) of triethanolamine in 30 mL of DMF, followed by agitation for 1 hour at 5° C. or lower and then agitated for 4 hours at room temperature was added in drops to the above selection. After the reaction, the precipitated crystals were obtained by filtration, washed with DMF and then with water, and were then dried, thus resulting in 8.54 g of the target substance.

Calculated values were C=73.8%, H=4.49%, and N=7.7%. Obtained values were C=72.9%, H=4.73%, and N=7.9%.

The azo compound of the present invention has excellent electroconductivity, enabling a photo-receptor for electrophotography of the present invention to be produced by providing a photosensitive layer, which allows said azo compound to be dispersed in a binder, on an eletroconductive support. The azo compound of the present invention can be formed into a so-called function-separating type of photo-receptor by using said azo compound as a carrier-generation substance utilizing its superior carrier-generating ability as well as by using conjunctively a carrier-transport substance that can act effectively in combination with the above mentioned azo compound. Although the above mentioned function-separating type of photo-receptor may be of a mixed dispersion type of said both substances, it is preferably lamination type of photo-receptor that ensures lamination of a carrier-generation layer containing a carrier-generation substance which contains the azo compound of the present invention and a carrier-transport layer containing a carrier-transport substance.

Photo-receptors for electrophotography of the present invention can be illustrated by, for example, one in which, as shown in FIG. 1, a photosensitive layer 4 of a laminated construction of the function-separating type is provided on a support 1 (which is an eletroconductive support or one with an eletroconductive layer provided on a sheet) with its lower layer being a carrier-generation layer 2 which contains a carrier-generation substance and, as occasion demands, a binder resin and with its upper layer being a carrier-transport layer 3 which contains a carrier-transport substance and a binder resin; one in which, as shown in FIG. 2, photosensitive layer 4 of a laminated construction is provided on said support 1 with its lower layer being carrier-transport layer 3 and with its upper layer being said carrier-generation layer 2; and one in which, as shown in FIG. 3, said photosensitive layer 4 containing a carrier-generation substance, a carrier-transport substance and a binder resin is provided on said support 1.

In case of a photosensitive layer of the laminated construction, the carrier-generation layer is preferably a layer which is made of the thinnest possible film within a range of thicknesses sufficient to generate photo-carriers to allow the great majority of the volume of incident light to be absorbed in a charge-generation layer, causing the generation of many charge-generation carriers, as well as allowing the generated charge carriers to be injected in the carrier-transport layer without suffering inactivation due to rebinding and trapping.

In addition, the carrier-transport layer is junctioned electrically with the above mentioned carrier-generation layer and is able to receive the charge carriers injected from the charge-generation layer in the presence of an electric field and is able to transport these charge carriers to its surface.

In the function-separating type of photo-receptor of a single-layer construction, furthermore, generation and transport of photo-carriers are performed with a single layer, in which a carrier-generation substance and a carrier-transport substance are electrically junctioned, and/or the carrier-generation substance also contributes to the transport of carriers.

Still further, the carrier-generation layer may contain both the carrier-generation substance and the carrier-transport substance. In any construction of layers, a protective layer may be provided on the photosensitive layer as illustrated in FIG. 7 or FIG. 9, and as further shown in FIG. 4 or FIG. 6, subbing layer (an intermediate layer) having a barrier function and adhesiveness may be provided between the support and the photosensitive layer.

Organic amines can be added into the photosensitive layers of the present invention to improve the carrier-generation function of the carrier-generation substances, the addition of secondary amines in particular being preferable.

These secondary amines can be illustrated by, for example, dimethylamine, di-n propylamine, di-isopropylamine, di-n butylamine, di-isobutylamine, di-n amylamine, di-isoamylamine, di-n hexylamine, di-isohexylamine, di-n pentylamine, di-isopentylamine, di-n octylamine, di-isooctylamine, di-n nonylamine, di-isononylamine, di-n decylamine, di-isodecylamine, di-n monodecylamine, di-isomonodecylamine, di-n dodecylamine, di-isododecylamine, etc.

Furthermore, the added amounts of the above mentioned organic amines as for each carrier-generation substance are equal to, or less than, that of the concerned carrier-generation substance, preferably in range of moles accounting for 0.2 times to 0.005 times the amounts of these substances.

In addition, 2 g of the illustrated compound No. I-71 and 2 g of a polycarbonate resin "PANLITE L-1250" (manufactured by Teijin Chemicals Ltd.) were added to 110 mL of 1,2-dichloroethane to be dispersed with a ball mill for 12 hours. The resulting dispersion solution was then applied to the above intermediate layer for a membrane thickness of 0.5 μm after drying, thus leading to the formation of the carrier-generation layer. A solution prepared by dissolving 6 g of a carrier-transport substance of the below specified structural formula (CT-1) and 10 g of the polycarbonate resin "PANLITE L-1250" in 80 mL of 1,2-dichloroethane was applied to this layer for a membrane thickness of 15 μm after drying, resulting in formation of the carrier-transport layer of a photo-receptor of the present invention. ##STR217##

After charging for 5 sec with a charge voltage of -6 kV, the photo-receptor was left dark for 5 sec and then exposed to 35 lux of halogen light, on the surface of the photo-receptor, thus resulting in the measurement of E 1/2, i.e., the amount of exposure needed to damp the surface potential to a half (half-life exposure). Further, after exposure with an exposure amount of 30 lux/sec, surface potential (residual potential) V_(R) was measured. The same measurement was repeated 100 times. The results are indicated in Table 1.

EXAMPLES 10 TO 12

The intermediate layer with a thickness of 0.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co., Ltd.) was provided on an eletroconductive support formed by laminating polyester film with aluminum, and in addition, 6 g of an illustrated compound No. I-147 and 2 g of the polycarbonate resin "PANLITE L-1250" were added to 110 mL of tetrahydrofuran and then dispersed with a ball mill for 12 hours. This dispersion solution was applied to the above intermediate layer to obtain a membrane thickness of 0.5 μm after drying, thus being formed into the carrier-generation layer.

EXAMPLE 13

The intermediate layer with a thickness of 0.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co., Ltd.) was provided onto the surface of an aluminum drum with a diameter of 60 mm and was then applied with a dispersion solution formed by mixing 2 g each of the illustrated compounds Nos. I-2, I-4, I-46, I-82 and I-154 and 2 g of a polyester resin "Vylon 200" (manufactured by Toyobo Co., Ltd.) with 110 mL of 1,2-dichloroethane for dispersion with use of a ball mill dispersion apparatus, so that the resulting layer would have a membrane thickness of 0.6 μm after drying, thus formating the carrier-generation layer.

In addition, 30 g of the below specified compound (CT-9) and 50 g of a polycarbonate resin "IUPILON S-1000" (Mitsubishi Gas Chemical Co., Ltd.) was dissolved in 400 mL of 1,2-dichloroethane, and the resulting solution was applied to the above carrier-generation layer to obtain a membrane thickness of 18 μm after drying, thus resulting in the formation of the carrier-transport layer as well as production of a drum-shape photo-receptor. ##STR223##

With the photo-receptor prepared by the above process mounted on a modified "U-Bix 1500 MR" electrophotographic copier (manufactured by Konica Co.), images were copied. The copied images were characterized by high contrast, high fidelity to the original photographs and great distinction as well. Image characteristics were unchanged even when the above operation was repeated 50,000 times.

COMPARATIVE EXAMPLE 3

A drum-shape photo-receptor for comparison was produced by the same process as described in Example 13 except for the replacement of the illustrated compounds in Example 13 with an azo compound represented by the below specified structural formula (CG-3), and the copied images obtained by use of the photo-receptor were evaluated in the same way as those in Example 13, resulting only in heavily fogged images. In addition, the contrast of the copied images decreased as copying was repeated, and hardly any image was copied when copying was repeated 10,000 times. ##STR224##

EXAMPLES 14 to 17

The intermediate layer with a thickness of 0.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co., Ltd.) was provided on an electroconductive support produced by laminating polyester film with aluminum foil, and a solution prepared by dissolving 6 g of the carrier-transport substance represented by the below specified structural formula (CT-10) and 10 g of the polycarbonate resin "PANLITE L-1250" in 80 mL of 1,2-dichloroethane was then applied to the above mentioned intermediate layer, thus leading to the formation of the carrier-transport layer. ##STR225##

Further, 2 g each of the illustrated compounds I-211, I-215, I-223 and I-231, and 1.5 g of the carrier-transport substance and 2 g of the polycarbonate resin "PANLITE L-1250" were added to 70 mL of 1,2-dichloroethane and 30 mL of 1,1,2-trichloroethane, then being dispersed for hours with a ball mill. The resulting solution was further applied to the above mentioned carrier-transport layer to be formed into the carrier-generation layer with a membrane thickness of 4 μm, thus to prepare respective photo-receptors of the present invention.

The measurements for these photo-receptors were conducted as described in Example 1. Results are shown in

EXAMPLE 22

The intermediate layer with a thickness of 1.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co., Ltd.) was provided on the surface of an aluminum drum with a diameter of 100 mm. Further, a dispersion solution was prepared by mixing 4 g of the illustrated compound No. I-220 with 400 mL of 1,2-dichloroethane and then dispersing the mixture for 24 hours with a ball mill dispersion apparatus. Then, the above dispersion solution was applied to the above intermediate layer for a membrane thickness of 0.6 μm after drying, to form the carrier-generation layer.

Still further, a solution formed by dissolving 30 g of a compound represented by the already described structural formula (K-9) and 50 g of a polycarbonate resin "IUPILON S-1000" (Mitsubishi Gas Chemical Co.) in 400 mL of 1,2 dichloroethane was applied to the above described carrier-generation layer for a membrane thickness of 13 μm after drying, and resulting in production of the carrier-transport layer, to prepare a drum-shape photo-receptor.

The photo-receptor thus created was mounted on a remodelled "LP-3010" electrophotographic printer (manufactured by Konica), resulting in high contrast, high fidelity to the original photographs and high-resolution copies. These phenomena were unchanged even when the operation was repeated 10,000 times.

COMPARATIVE EXAMPLE 5

A drum-shape photo-receptor was produced by the same process as in Example 22 except using a bis-azo compound expressed by the below specified structural structure instead of the carrier-generation substance in Example 22, and the copied images for said photo-receptor for comparison were evaluated by the same method as in Example 22, resulting in heavily-fogged images. As photographs were being copied repeatededly, in addition, the contrast of the copied images was increased, and no copied image was obtainable after 2,000 copies. ##STR229##

As clearly understandable from the results of the above mentioned Examples and Comparative Examples, the photo-receptors of the present invention have superior stability, sensitivity, and durability in combination with a wide variety of carrier-transport substances than the photo-receptors used for comparison.

EXAMPLE 23

An intermediate 0.05 μm layer made of vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co.) was distributed onto an electroconductive support composed of polyester film laminated with aluminum foil. Then 2 g of the illustrated compound No. II-7 and 2 g of polycarbonate resin "PANLITE L-1250" (manufactured by Teijin Chemicals Ltd.) were added to 110 mL of 1,2-dichloroethane and dispersed with a ball mill for 12 hours. This dispersion solution was applied to the above mentioned intermediate layer to build up a dry membrane thickness of 0.5 μm thus forming a carrier-generation layer. Further, 6 g of a compound of the below specified structural formula (K-1) as a carrier-transport substance and 10 g of a polycarbonate resin "PANLITE L-1250" were dissolved in 80 mL of 1,2-dichloroethane, and the resulting solution was applied to the above mentioned carrier-generation layer to build up a membrane thickness of 15 μm after drying for formation of a carrier-transport layer, resulting in a photo-receptor of the present invention. ##STR230##

The photo-receptor prepared by the above process was analyzed to evaluate its properties using an SP-428 model electrostatic paper analyzer manufactured by Kawaguchi Electric Works Co. After charging for 5 sec with a charged voltage of -6 kV, the above photo-receptor was left dark for 5 sec and was then exposed 35 lux hologen light on the surface of the pohoto-receptor, thus leading to the measurement of E 1/2, an amount of exposure that is necessary to allow the surface potential to decay to a half (half-life exposure). Another measurement was V_(R), the surface potential after exposure to 30 lux sec (residual potential). The same measurements were further repeated 100 times. Results are shown in Table 8.

COMPARATIVE EXAMPLE 6

A photo-receptor for comparison was produced by the same process as in Example 23 except that the following bis-azo compound (G-1) was used as a carrier-generation substance. ##STR231##

The measurements shown in Example 23 were performed for the above photo-receptor for comparison, resulting in the data shown in Table 8.

As shown in the above results, the photo-receptor of the present invention has superior sensitivity, residual potential and stability in repetition than the photo-receptor used for comparison.

EXAMPLES 40 TO 45

An intermediate layer with a thickness of 0.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co.) was distributed on the surface of an aluminum drum with a diameter of 60 mm. In addition, 2 g each of the illustrated compounds Nos. II-96, II-301, II-659, II-668, II-675 and II-680 and 2 g of a polyester resin "VYLON 200" (manufactured by TOYOBO Co., Ltd.) were mixed with 110 mL of 1,2-dichloroethane to be dispersed with a ball mill dispersion apparatus for 24 hours. This dispersion solution was then applied to the intermediate layer described above to build up a membrane thickness of 0.6 μm for formation of the respective carrier-generation layers.

In addition, 30 g of the below specified compound (K-9) and 50 g of a polycarbonate resin "IUPILON S-1000" (manufactured by Mitsubishi Gas Chemical Co.) were dissolved in 400 mL of 1,2-dichloroethane, and the resulting solution was applied to the respective carrier-generation layers described above to form the respective carrier-transport layers, thus allowing the drum-shape photoreceptors 40 to 45 to be prepared respectively. ##STR236##

The photo-receptors prepared as described above were mounted on a modified "U-Bix 1550 MR" electrophotographic copier (manufactured by Konica) to copy pictures, creating the copies that exhibited high contrast, good reproducibility of the orignal picture, and excellent visibility in all the cases of the above photo-receptors. This performance, in addition, showed no change even when copying was repeated 50,000 times.

COMPARATIVE EXAMPLE 8

A Drum-shape photo-receptor for comparison was prepared by the same process as in Examples 40 to 45 except replacing one of the illustrated compounds in Examples 40 to 45 with a bis-azo compound represented by the below specified structural formula, and the copied picture was evaluated by the same method as that used in Examples 40 to 45, resulting in only those copies having much fog. When the picture was repeatedly copied, the contrast of the copied picture was deteriorated, and 5,000 copy repetitions resulted in almost no formation of the copied picture. ##STR237##

Furthermore, 2 g each of illustrated compounds II-203, II-227, II-441, II-665 and II-673, 1.5 g of the carrier-transport substance described above and 2 g of a polycarbonate resin "PANLITE L-1250" were added to 70 mL of 1,2-dichloroethane and 30 mL of 1,2-trichloroethane for dispersal with a ball mill for 24 hours, and each resulting dispersion solution was applied to the above mentioned carrier-transport layer to build up a dry membrane thickness of 4 μm for formation of a carrier-generation layer, thus resulting in creation of the photo-receptors 46 to 50, respectively.

The measurements were carried out by the same method as that in Example 23 for the above respective photo-receptors, and the data shown in Table 12 was obtained.

In addition, 2 g of the illustrated compound No. III-8 and 2g of polycarbonate resin "PANLITE L-1250" (manufactured by Teijin Chemicals Ltd.) were added to 110 mL of 1,2-dichloroethane for dispersal in with a ball mill for 12 hours. This dispersion solution was applied to the above mentioned intermediate layer to build up a dry membrane thickness of 0.5 μm for formation of a carrier-generation layer. In addition, a mixed solution of 6 g of a compound expressed by the below specified structural formula (K-1) as a carrier-transport substance and 10 g of a polycarbonate resin "PANLITE L-1250" with 80 mL of 1,2-dichloroethane was applied to the carrier-generation layer described above to build up a dry membrane thickness of 15 μm for formation of a carrier-transport layer, thus resulting in the production of a photo-receptor of the present invention. ##STR239##

The photo-receptor fabricated by the process described above was analyzed for the following evaluation of properties using an SP-428 model electrostatic paper analyzer manufactured by Kawaguchi Electric Works Co. The photo-receptor was charged for 5 sec with a charged voltage of -6 kV and was then left dark for 5 sec, followed by exposure to the light of a halogen lamp so that the intensity of illumination would become 35 lux on the surface of the photo-receptor, then leading to the measurement of E 1/2, an amount of exposure that was necessary to allow the surface potential to decay to a half (half-life exposure). Another measurement was made for V_(R), a surface potential after exposure with an exposure amount of 30 lux sec (residual potential). The same measurements were repeated 100 times. The results are exhibited in Table 13.

EXAMPLES 64 TO 66

An intermediate layer with a thickness of 0.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC FM-10" (manufactured by Sekisui Chemical Co.) was provided an electroconductive support composed of polyester film laminated with aluminum foil. Further, 2 g of the illustrated compound No. III-286 and a polycarbonate resin "PANLITE L-1250" were added to 110 mL of tetrahydrofuran to be dispersed with a ball mill for 12 hours. This dispersion solution was then applied to the above intermediate layer to build up a membrane thickness of 0.5 μm after drying for formation of a carrier-generation substance. Still further, 6 g each of the respective compounds expressed by the below specified structural formulae (K-6), (K-7) and (K-8) as carrier-transport substances and 10 g of a polycarbonate resin "Z-200" (manufactured by Mitsubishi Gas Chemical Co.) were dissolved in 80 mL of 1,2-dichloroethane, and the resulting solution was applied to the carrier-generation substance described above to form a carrier-transport layer, thus leading, to prepare photo-receptors for the present invention. ##STR244##

EXAMPLE 67

An intermediate layer with a thickness of 0.05 μm made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co.) was distributed on the surface of an aluminum drum having a diameter of 60 mm. A disperson solution was then prepared by mixing 2 g of the illustrated compound No. IV-223 and 2 g of a polyester resin "VYLON 200" (manufactured by TOYOBO Co.) with 110 mL of 1,2-dichloroethane and allowing the mixture to be dispersed with a ball mill dispersion apparatus for 24 hours. The dispersion solution was applied to the intermediate layer desribed above to form a carrier-generation layer with a dry membrane thickness of 0.6 μm.

Furthermore, a mixed solution of 30 g of the following specified compound (K-9) and 50 g of a polycarbonate resin "IUPILON S-1000" (Mitsubishi Gas Chemical Co.) with 400 mL of 1,2-dichloroethane was applied to the carrier-generation layer described above to form a carrier-tranport layer with a dry membrane thickness of 18 μm thus resulting in the formation of a drum-shape photo-receptor. ##STR245##

The photo-receptor formed as described above was mounted on a modified "U-Bix 1550 MR" electrophotographic copier (manufactured by Konica) to copy images. The copied images had high contrast and good reproducibility of the original picture and visibility as well. There was no change in this performance even when copying was repeated 50,000 times.

COMPARATIVE EXAMPLE 15

A drum-shape photo-receptor for comparison was prepared by the same process as described in Example 67 except that the illustrated compound described in Example 67 was replaced with an azo compound represented by the below specified structural formula (G-3), and the copied pictures were evaluated by the same method as that in Example 67, resulting in only those having much fog. As copying was repeated, in addition, the contrast of the copied pictures deteriorated, leading to little reproduction of the original picture after 5,000 copies. ##STR246##

EXAMPLE 68

An intermediate 0.05 μm layer made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co.) was distributed on an electroconductive support composed of polyester film laminated with aluminum foil. Then, 6 g of a compound expressed by the below structural formula (K-10) as a carrier-transporting substance and 10 g of a polycarbonate resin "PANLITE L-1250" were dissolved in 80 mL of 1,2-dichloroethane, and the resulting solution was applied to the intermediate layer described above to build up a dry membrane thickness of 15 μm, thus forming a carrier-transport layer. ##STR247##

Furthermore, 2 g of the illustrated compound No. III-21, 1.5 g of the above mentioned carrier-transport substance 2 g of a polycarbonate resin "PANLITE L-1250" were added to 70 mL of 1,2-dichloroethane and 30 mL of 1,2-trichloroethane and were dispersed with a ball mill for 24 hours. This dispersion solution was then applied to the above mentioned carrier-transport layer to build a carrier-generation layer with a dry membrane thickness of 4 μm leading to the completion of a photo-receptor.

The measurements were performed for this photo-receptor as described in Example 51, resulting in the data revealed in Table 17.

                  TABLE 17                                                         ______________________________________                                                     1st time                                                                              100th time                                                  ______________________________________                                          E 1/2        1.1      1.4                                                     (lux/sec)                                                                      V.sub.R (V)   0        0                                                       ______________________________________                                    

As clarified by the results of the above mentioned Examples and Comparative Examples, the photo-receptors of the present invention have superior stability, sensivity, durability, and ability to combine with a wide variety of carrier-transporting substances, than the photo-receptors used for comparison.

EXAMPLE 69

An intermediate 0.05 μm layer made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "S-LEC MF-10" (manufactured by Sekisui Chemical Co.) was distributed on an electroconductive support composed of polyester film laminated with aluminum foil, and 2 g of the illustrated compound expressed by General formula [A] and 2 g of a polycarbonate resin "PANLITE L-1250" (Teijin Chemicals Ltd.) were then added to 110 mL of 1,2-dichloroethane and dispersed with a ball mill for 12 hours. This dispersion solution was further applied to the above intermediate layer to build up a dry membrane thickness of 0.5 μm, to form a carrier-generation layer. In addition, a mixed solution of 6 g of the following structural formula (K-1) compound as a carrier-transport substance and 10 g of a polycarbonate resin "PANLITE L-1250" with 80 mL of 1,2-dichloroethane was applied to the above carrier-generation layer to build up a 0.5 μm dry membrane thickness to form of a carrier-transport layer, thus resulting in the production of the photo-receptor of the present invention. ##STR248##

The photo-receptor obtained as described above was analyzed for the following evaluation of properties by use of an EPA-8100 model electrostatic paper analyzer. After charging for 5 sec with a charged voltage of -6 kV, the photo-receptor was left dark for 5 sec and was exposed a hologen lamp at 35 lux sec on the surface of the photo-receptor, thus leading to the measurement of E 1/2, an amount of exposure that was necessary to allow the surface potential to decay to a half (half-life exposure). Another measurement was V_(R), a surface potential after exposure with an amount of 30 lux sec (residual potential). The same measurements were repeated 100 times. Results are as indicated in Table 18.

COMPARATIVE EXAMPLE 16

A photo-receptor for comparison was formed by the same process as in Example 69 except using the below specified bis-azo compound (G-1) as carrier-generation substance. ##STR249##

EXAMPLE 90

An 1.05 μm intermediate layer made of a vinyl chloride-vinyl acetate-maleic anhydride copolymer "SS-LEC MF-10" (manufactured by Sekisui Chemical Co.) was distributed onto the surface of an aluminum drum with a diameter of 100 mm. Further, 4 g of the illustrated compound I033 represented by General formula [L] was mixed with 400 mL of 1,2-dichloroethane and dispersed with a ball mill dispersion apparatus for 24 hours, and the resulting dispersion solution was applied onto the intermediate layer described above to build up a dry membrane thickness of 0.6 μm to form a carrier-generation layer.

Futhermore, a mixed solution of 30 g of a compound of the already set forth structural formula (K-9) and 50 g of a polycarbonate resin "IUPILON S-1000" (manufactured by Mitsubishi Gas Chemical Co.) with 400 mL of 1,2-dichlorethane was applied onto the above mentioned carrier-generation layer to build up a carrier-transport layer with a dry membrane thickness of 13 μm thus resulting in the preparation of a drum-shape photo-receptor.

The photo-receptor produced as mention above was mounted on a modified "LP-3010" an electrophotographic copier (manufactured by Konica) to create copied pictures, which proved to be characterized by high contrast, good reproducibility of the original picture and fine visibility. In addition, no change in these characteristics was caused by copying 10,000 times.

COMPARATIVE EXAMPLE 20

A drum-shape photo-receptor for comparison was formed as described in Example 84 except that the carrier-generating substance was replaced with a bis-azo compound expressed by the below specified structural formula (G-5) in Example 83, and the copied pictures were evaluated by the same method as in Example 83, resulting in heavily fogged copies. In copying repeatedly, in addition, the contrast of the copied image increased, leading to little availability of the copied image after 2,000 repetitions. ##STR260##
